This study aims to examine the problem of taking global cybercriminals and examine solutions to applying the Aut Dedere Aut Judicare principle through the ratification of the Budapest Convention. The research method used in this study is normative legal research with a regulatory approach, cases, and comparative analysis. The study results indicate that Indonesia does not yet have a special regulation regulating cybercrimes; however, two rules cover cybercrimes offences, namely, the Criminal Code and the ITE Law. However, these two regulations can still not deal with transnational cybercriminals specifically for fun issues. Therefore, applying the Aut Dedere Aut Judicare principle through the Budapest Convention ratification becomes urgent for implementation. The Aut Dedere Aut Judicare principle states that every country will understand with other countries to arrest, prosecute and prosecute perpetrators of international crimes. So it is necessary to ratify the Budapest Convention as a legal basis to apply the Aut Dedere Aut Judicare principle.
